为研发防治小麦赤霉病的新药剂,采用菌丝生长速率法分别检测了丙硫菌唑、丙环唑及其7种配比混剂对赤霉病菌的室内毒力,并进行了优选配比制剂对赤霉病、籽粒DON毒素、白粉病和叶锈病的田间药效试验.结果表明,丙硫菌唑与丙环唑配比为1∶1时增效系数为2.4375,增效最显著.田间药效试验中,40％丙硫菌唑·丙环唑可分散油悬浮剂(OD)600 g/hm2对赤霉病病指防效和籽粒DON防效分别为93.46％和91.26％,2次药后21 d对白粉病和叶锈病病指防效分别为93.50％和93.19％,均高于常规药剂戊唑醇和多菌灵,并且对小麦生长安全.40％丙硫菌唑·丙环唑OD对赤霉病和籽粒DON毒素防效优良,同时对白粉病和叶锈病兼治效果优良,具有较好的开发潜力.
Co-toxicity and Field Control Efficacy of Mixtures of Prothioconazole and Propiconazole to Fusarium Head Blight Caused by Gibberella zeae(Schw.)Petch
In order to explore a new reagent for controlling fusarium head blight(FHB),the indoor toxicity of prothioconazole,propiconazole and their seven mixtures on Gibberella zeae(Schw.)Petch had been detected by using mycelium growth rate method.Meanwhile,the field control tests of the optimum formulation on FHB,DON in wheat grain,wheat powdery mildew(WPM)and wheat leaf rust(WLR)had been conducted,respectively.The results of indoor toxicity tests showed that the synergistic coefficient was 2.4375 when the mixture of prothioconazole and propiconazole at the ratio of 1∶1,and the synergistic effect was the most significant.The results of the field control efficacy showed that the FHB disease index(DI)and DON control efficacy of 40％prothioconazole·propiconazole oil dispersion(OD)600 g/hm2 were 93.46％and 91.26％,respectively,while the control efficacy against WPM DI and WLR DI on the 21th day after 2 times of spraying were 93.50％and 93.19％,respectively,both of which were higher than the control efficacy of the common fungicide tebuconazole or carbendazim,and it was safe for wheat growth.40％prothioconazole·propiconazole OD provided excellent control efficacy on FHB and DON in wheat grain,as well as excellent simultaneous control efficacy on WPM and WLR,which had good development potential.
